Abstract

We demonstrate ultrasonic welding for (1) self-aligned gapless bonding of a two-part lab-on-a-chip system and for (2) bonding of a large area shallow chamber. Combining injection moulding using micromilled shims with ultrasonic welding, we can go from design to a batch of chips within a single day. The chips are mass-producible with a total production time of 60 s per chip.
